Cloudera excels at seamless migrations and upgrades. Cloudera supports self-healing and data centerreplacement of failed cloud instances while maintaining the state. Cloudera is essential to increase or decreasecapacity through the user interface or API. Cloudera is great at simplifying big data analyticsby providing the technology and tools needed to gain insights from IoT andconnected devices to help monitor and condition our assets. Cloudera's cybersecurity platform option offersstronger anomaly detection, visibility, and prevention, as well as fasterbehavioral analysis. Cloudera is beneficial for enabling and utilizingthe platform's machine learning and ad-hoc queries while securely storing,retrieving, and analyzing any volume of data at scale.Incentivized
The company has been using it for many years and I have been using it for just over 2 years. I feel the ease in obtaining the data. The solution can fit scenarios where there is quite a high workload and a low response time. Queries and transactions occur in milliseconds. Other backup/restore, replication and other features are fundamental and work exceptionally well. IBM is one of the most reliable companies and has been in the market for years in this segment and has helped us with support whenever we need it.Incentivized
Excellent management capabilities via Cloudera Manager.Open source and does not restrict our data to be bound by a proprietary format.Offers excellent support for data governance and auditing.Has all the components that would help us build a data hub.Excellent platform support offered by Cloudera.
DB2 maintains itself very well. The Task Scheduler component of DB2 allows for statistics gathering and reorganization of indexes and tables without user interaction or without specific knowledge of cron or Windows Task Scheduler / Scheduled jobs.Its use of ASYNC, NEARSYNC, and SYNC HADR (High Availability Disaster Recovery ) models gives you a range of options for maintaining a very high uptime ratio. Failover from PRIMARY to SECONDARY becomes very easy with just a single command or windowed mouse click.Task Scheduler ( DB2 9.7 and earlier ) allows for jobs to be run within other jobs, and exit and error codes can define what other jobs are run. This allows for ease of maintenance without third party softwares.Tablespace usage and automatic storage help keep your data segmented while at rest, making partitioning easier.Ability to run commands via CLI (Command Line Interface) or via Control Center / Data Studio ( DB2 10.x+) makes administration a breeze.Incentivized
Not fully Open Source, couple of components of the distributions are privately owned, meaning with public contributions are not welcomeImprovements to Cloudera manager can only be recommended. its very hard to get it done once recommended as the full control is with them.Should make components more aligned to Open Source rather than making it closed sourced.Custom Features of open source software tools supported only by Cloudera are tricky. Cant commit changes to tools like Hue.Improvements to Cluster Management tool is required, which are already available to its competitors.Incentivized
The relational model requires a rigid schema that does not necessarily fit with some types of modern development.Proprietary database, requires a lot of Hardware for its good performance and its costs are high.As data grows in production environment, it becomes slow.Incentivized
Likely to renew the use in case the requirements for Cloudera remain valid. The rapid change in customer requirements and solutions that must be validated, integrated or tested changes. As the maturity of the solution increases, the requirements to renew use decrease. From a solution feature perspective by itself would probably grade 10.
Since our services are running in IBM Kubernetes, using IBM Cloud Databases seem to be the best option. It may provide better performance than other vendors as everything is running in the same cloud. The overall experience so far is good as well.Incentivized
You have to be well versed in using the technology, not only from a GUI interface but from a command line interface to successfully use this software to its fullest.Incentivized
Any issues related to DB2's availability are usually resolved easily and fast. We also have a team of dedicated analysts and admins to support the database technically. Once in a while we do request support from IBM for some complex issues that the on premise team can't resolve and the response is usually pretty fast and support is amazing!Incentivized
The performances are exceptional if you take care to maintain the database. It is a very powerful tool and at the same time very easy to use. In our installation, we expect a DB machine on the mainframe with access to the database through ODBC connectors directly from branch servers, with fabulous end users experience.Incentivized
Easily the best product support team. :) Whenever we have questions, they have answered those in a timely manner and we like how they go above and beyond to help.Incentivized
Cloudera iscompatible with Windows operating systems, and Mac allows cloud-baseddeployment, it is also very useful to configure data encryption, guaranteeprotocols, and security policies. It also provides integrated auditing andmonitoring capabilities, as well as a control comprehensive data repository forthe enterprise, and ensures vendor compatibility through its open-sourcearchitecture.Incentivized
Db2 is one of the best relational databases I’ve used. It has the ability to maintain large amount of data and execution of million transactions in fraction of a second. If you use it properly, an organization can build a database with thousands of tables, and it can provide the exact information for the applications within a short amount of time Incentivized
Byusing DB2 only to support my IzPCA activities, my knowledge hereis somewhat limited. Anyway,from what I was able to understand, DB2 is extremely scallable. Maybe the information below could serve as an example of scalability. Customer have an huge mainframe environment, 13x z15 CECs, around80 LPARs, and maybe more than 50 Sysplexes (I am not totally sure about thislast figure...) Todaywe have 7 IzPCAdatabases, each one in a distinct Syplex. Plansare underway to have, at the end, an small LPAR, with only one DB2 sub-system,and with only one database, then transmit the data from a lot of other LPARs,and then process all the data in this only one database. TheIzPCA collect process (read the data received, manipulate it, and insert rowsin the tables) today is a huge process, demanding many elapsedhours, and lots of CPU. Almost100% of the tables are PBR type, insert jobs run in parallel, but in 4 of the 7database, it is a really a huge and long process. Combiningthe INSERTs loads from the 7 databases in only one will be impossible.......,,,, But,IzPCA recently introduced a new feature, called "ContinuousCollector". Byusing that feature, small amounts of data will be transmited to the centralLPAR at every 5 minutes (or even less), processed immediately,ina short period of time, and with small use of CPU,instead of one or two transmissions by day, of very large amounts of data andthe corresponding collect jobs occurring only once or twice a day, with longelapsed times, and huge comsumption of CPU Isuspect the total CPU seconds consumed will be more or less the same inboth cases, but in the new method it will occur in small burstsmany times a day!!Incentivized
Cloudera products are the most widely. It is more business friendly as data is more secure. The sensitive data that you operate on is local to you and your project rather than processing this data on Cloud.Cloudera is definitely faster as wait time is reduced if on Cloud.A lot range of products are covered. So it is definitely good for businesses and had good returns on investments.
Has reduced the downtime or outages due to HADR features which we lagged earlier.No manual intervention needed in most situation for us. IN worst case TSA does automatic failover so its transparent for the apps.LOB support is little bit problem for us now which we hope will have some improvement in product in future.Incentivized
